System for remote control of production equipment and management method therefor

Abstract

A system checks for abnormality in a machine tool and regardless of power interruption of the machine tool. A system for remote control of production equipment is installed in a management apparatus for the production equipment by receiving operational state information of a machine tool and transmitting the data thereof to a server. The system includes at least one sensor installed in the main body of the machine tool to collect operational information data thereof and transmit the same to the server. The sensor includes a dual power supply having a first external power source supplied with external power in communication with the machine tool and a second power source formed of a battery independent of the external power. A sensor communication network transmits the collected data to the server, whereby causes of failure may be judged by determining whether data communication with the server is executed.

1 . A system for remote control of production equipment, which is installed in a management apparatus for the production equipment to receive operational state information of a machine tool and transmit data to a server so as to manage the production equipment, comprising:
 at least one sensor which is provided in a main body of the machine tool to collect operational information of the machine tool in real time and transmit the same to the server, wherein the at least one sensor includes:
 a dual power supply including a first external power source supplied with external power in communication with the machine tool, and a second power source having a battery independent of the external power; and 
 a sensor communication network to transmit the collected data to the server through wire or wirelessly, whereby causes of a failure are judged by determining whether data communication with the server is executed or not. 
   
     
     
         2 . The system according to  claim 1 , wherein the dual power supply supplies power to a board by activating a switch depending on the power source. 
     
     
         3 . The system according to  claim 1 , wherein the sensor communication network includes:
 a detection sensor to receive the operational state information of the machine tool;   a converter ADC; and   a wired/wireless transmission unit for communicating with the server.   
     
     
         4 . The system according to  claim 1 , wherein the sensor communication network allows:
 transmission of data from the detection sensor, which receives the operational state information of the machine tool, through wire by the wired/wireless transmission unit, when power is supplied by the first external power source; and   wireless transmission of data from the detection sensor, which receives the operational state information of the machine tool, by the wired/wireless transmission unit, when power is supplied by the second power source.   
     
     
         5 . A management method for remote control of production equipment, comprising:
 determining whether power is supplied by an external power source to supply power to the machine tool or by an internal battery;   when the power is supplied by the external power source, transmitting data from the detection sensor provided with the operational information of the machine tool to the server by wire; and   when the power is supplied by the internal battery, wirelessly transmitting data from the detection sensor provided with the operational information of the machine tool, thereby determining whether there is data communication of the server.   
     
     
         6 . The system according to  claim 2 , wherein the sensor communication network allows:
 transmission of data from the detection sensor, which receives the operational state information of the machine tool, through wire by the wired/wireless transmission unit, when power is supplied by the first external power source; and   wireless transmission of data from the detection sensor, which receives the operational state information of the machine tool, by the wired/wireless transmission unit, when power is supplied by the second power source.   
     
     
         7 . The system according to  claim 3 , wherein the sensor communication network allows:
 transmission of data from the detection sensor, which receives the operational state information of the machine tool, through wire by the wired/wireless transmission unit, when power is supplied by the first external power source; and   wireless transmission of data from the detection sensor, which receives the operational state information of the machine tool, by the wired/wireless transmission unit, when power is supplied by the second power source.
